More Crashes at 20mph

Published Date: 7th Jul 2014

The number of serious crashes on 20mph roads shot up by 26% in 2013, according to the Institute of Advanced Motorists (IAM).

The road safety organisation also found that less serious accidents in 20mph zones increased by 17% - but the number of serious and not-so-serious crashes in 30mph and 40mph limits dropped.

Some people would say that this proves that faster speed limits are safer than 20mph limits, but in reality it’s probably because more roads are being given low speed limits.

Simon Best, IAM chief executive, explained:

“The government and councils need to take stock on the effectiveness of 20mph signs.  Recent advice, guidance and relaxation of regulations have all been about making it easier for councils to put 20mph limits in place.

“More and more roads are being given a 20mph limit but they do not seem to be delivering fewer casualties. The IAM are concerned that this is because simply putting a sign on a road that still looks like a 30mph zone does not change driver behaviour.”

Charity “Brake“claims 20mph zones reduce accidents

The research by the IAM contradicts that by road safety charity Brake, which found that large areas with widespread 20mph zones saw large reductions in crashes.

Brake launched a GO 20 campaign in April 2014 and called on MPs to change the default urban speed limit to 20mph. It provided information from Camden, that the London borough saw a 54% fall in crashes after introducing 20mph zones.

At the time, Brake deputy chief executive, Julie Townsend, explained:

“The GO 20 campaign is about defending everyone’s right to walk and cycle freely without being endangered, whether it’s to get to work, school, the shops, or just getting out and being active.

“With many people already reaping the benefits of living in 20mph areas, we’re reaching a point where it makes no sense to retain 30mph as the default limit in built-up areas. It’s time for the government to GO 20 nationally, to save councils money and help create safe, active, happy communities nationwide.”
